The Power Plant garden at the National Arboretum in Washington, D.C., displays a variety of plants that may provide a valuable and renewable source of bioenergy for America. Bioenergy is a renewable energy made available from materials derived from biological sources. Miscanthus is a grass native to subtropical and tropical areas of Africa and southern Asia and could be important in the production in cellulosic ethanol. It is a giant among grasses growing to a height of 14 feet and could produce twice as much biomass as switchgrass. It takes three years before miscanthus is mature enough for harvesting and its low mineral content actually improves fuel quality. This photograph shows Miscanthus growing in the Power Plant garden at the National Arboretum in Washington, D.C. on August 19, 2008. USDA photo by Bob Nichols.
